My leaves are turning bright yellow

My plants are turning yellow. They are 2nd week of flower. Fox farm nutes. 3 gallon smart pots. Is it the cal mag? Should i flush? Or transplant to 5g pots.

New growth going on there. Add a little calmag to your water. It will be just fine. Just growing fast.

You have burnt tips, and what looks to be like so nitrogen toxicity from the clawing of your leaves. What were your runoff numbers from your last feed? What nutrients do you use(I know you use FF, but what bottles)? How strong is your mix(ppm) going in and what is your ph?
